  DetNet Packet Jitter, Bandwidth and Misordering Passive Performance

Abstract

   Deterministic Networking (DetNet) can provide data transmission with
   end-to-end bounded latency and extremely low packet loss for user's
   services.  In order to better control and manage deterministic
   network services.  It is necessary to measure and monitor DetNet QoS
   information.  As introduced in [I-D.chen-detnet-loss-delay], packet
   loss rates and end-to-end delay can be measured by using passive
   Performance Measurement (PM) in MPLS-based DetNet encapsulation.

   This document implement three new QoS related attribute to support
   passive Performance Measurement for DetNet service.

1.  Introduction

   As defined in [I-D.ietf-detnet-architecture], DetNet can provide data
   transmission with end-to-end bounded latency and extremely low packet
   loss for user's services.  In order to ensure the efficiency and
   accuracy of information collection and management, it is necessary to
   measure and monitor DetNet QoS information.

   DetNet QoS information includes minimum and maximum delay, bounded
   jitter, packet loss ratio and an upper bound on misordering packet in
   general.  Apart from this, link bandwidth information also play an
   important role in resource allocation.

   As introduced in [I-D.chen-detnet-loss-delay], packet loss rates and
   end-to-end delay can be measured by using passive Performance
   Measurement (PM) in MPLS-based DetNet encapsulation.  Which defines
   two new flags in the d-CW(control word) and three new TLVs to LM and
   DM messages.
